I tried my code, it works but the fangriders instantly override my griffins and kill them, it’s all downhill from there… Is there a problem with my code?

```python
def chooseStrategy():
    enemies = hero.findEnemies()
    enemy = hero.findNearest(enemies)
    # If you can summon a griffin-rider, return "griffin-rider"
    if hero.gold > hero.costOf("griffin-rider"):
        return "griffin-rider"
    # If there is a fangrider on your side of the mines, return "fight-back"
    elif enemy and enemy.type == 'fangrider' and self.distanceTo(enemy) < 30:
        return "fight-back"
        # Otherwise, return "collect-coins"
    else:
        return "collect-coins"

def commandAttack():
    # Command your griffin riders to attack ogres.
    for griffin in self.findByType("griffin-rider"):
        if griffin:
            enemy = griffin.findNearest(griffin.findEnemies())
            if enemy:
                self.command(griffin, "attack", enemy)
    pass
    
def pickUpCoin():
    # Collect coins
    bestRatio = 0
    bestCoin = None
    for coin in hero.findItems():
        coinRatio = coin.value / hero.distanceTo(coin)
        if coinRatio > bestRatio:
            bestRatio = coinRatio
            bestCoin = coin
            distanceCoin = hero.distanceTo(bestCoin)
            if bestCoin and hero.isReady("jump") and distanceCoin >= 10:
                hero.jumpTo(bestCoin)
                hero.move(bestCoin.pos)
            elif bestCoin:
                hero.move(bestCoin.pos)
            
    pass
    
def heroAttack():
    # Your hero should attack fang riders that cross the minefield.
    enemy = hero.findNearest(hero.findEnemies())
    distance = hero.distanceTo(enemy)
    if enemy and distance > 30:
        hero.attack(enemy)
    pass
    
while True:
    commandAttack()
    strategy = chooseStrategy()
    # Call a function, depending on what the current strategy is.
    if strategy == "griffin-rider":
        hero.summon("griffin-rider")
    if strategy == "fight-back":
        heroAttack()
    if strategy == "collect-coins":
        pickUpCoin()

```

Please post your code as explained above. There are many people here willing and able to help but there is a very tiny degree of effort required on your part to enable them to do so. It’s really easy but you’re going to have to read and follow the directions above.

My problem is that it cannot read type of null in the line: enemy = hero.findNearest(hero.findEnemies()) and I don’t know why this is wrong.

</div>

From now on, please copy the code **_from the game_** , **not** from here. Once you pasted it here, the formatting is gone.

If you’re receiving a null error, it’s probably because you don’t check for an enemy before checking for enemy.type. Try:

```python
if enemy and enemy.type == "munchkin":

```

or

```python
if enemy:
    if enemy.type == "muchkin":
        self.command(friend, “attack”, self.findNearest(self.findByType(“munchkin”)))
    elif enemy.type == "ogre":

```

Either way, make sure you check for the existence of an enemy first.

Thank you for trying to post your code properly. Next time just copy it from the game, not from here.

From what I could see, the griffin riders will only attack one enemy at a time. You don’t have to define `hero.findEnemies()` twice. You only attack the enemies who’s type is not fang-riders in what I could see. So then change the `if enemy.type == "whatever the enemy type is"` to `if enemy.type != "fangrider"`. They will only target one enemy, so change `enemy = hero.findNearest(hero.findEnemies())` to `enemy = friend.findNearestEnemy()`.

Wouldn’t it be great if people read directions first? It seems like I have to post this at least once a day.
